Abstract

A structure of signal transmission line has a core portion, a middle material layer and a coating layer. The core portion includes at least one transmission medium enveloped with an insulation layer. The coating layer includes at least one layer. The middle material layer is provided between the core portion and the coating layer, and has at least a metallic-wire knitting layer and a paper wrapping layer.

Claims

1. A signal transmission line comprising:

a) a core portion having a transmission media including;

i) a first conductor plated with pure silver;

ii) a PE insulation layer covering the first conductor;

iii) a second conductor made of pure copper of single crystal in single direction coated with lacquer, the second conductor covering the PE insulation layer; and

iv) a PE foam layer covering the second conductor;

b) a middle material layer formed on the core portion, the middle material layer having;

i) a PVC conductive layer;

ii) a metallic-wire knitted layer; and

iii) a paper wrapping layer; and

c) at least one coating layer formed on the middle material layer.

2. The signal transmission line according to claim 1, wherein the metallic-wire knitted layer is coated with silver.

3. A signal transmission line comprising:

a) a core portion having a transmission media including;

i) a first conductor plated with pure silver;

ii) a PE insulation layer covering the first conductor;

iii) a second conductor made of pure copper of single crystal in single direction coated with lacquer, the second conductor covering the PE insulation layer; and

iv) a PE foam layer covering the second conductor;

b) a middle material layer formed on the core portion, the middle material layer having;

i) a PVC conductive layer;

ii) a first metallic-wire knitted layer;

iii) a PTFE layer; and

iv) a second metallic-wire knitted layer; and

c) at least one coating layer formed on the middle material layer.

4. The signal transmission line according to claim 3, wherein the first and second metallic-wire knitted layers are coated with silver.

5. A signal transmission line comprising:

a) a core portion having two transmission media, each transmission media including;

i) a first conductor plated with pure silver;

ii) a PE insulation layer covering the first conductor;

iii) a second conductor made of pure copper of single crystal in single direction coated with lacquer, the second conductor covering the PE insulation layer; and

iv) a PE foam layer covering the second conductor;

b) a middle material layer formed on the core portion, the middle material layer having;

i) two PVC conductive layers;

ii) a cotton yarn filled layer;

iii) a metallic-wire knitted layer; and

iv) a paper wrapping layer; and

c) at least one coating layer formed on the middle material layer, such the two transmission media transmit signals of high and low frequencies separately.

6. The signal transmission line according to claim 5, wherein the metallic-wire knitted layer is coated with silver.
